Flow-coating apparatus and flow-coating method

A flow-coating apparatus, configured to flow-coat a member to be flow-coated with an insulation layer, wherein the member to be flow-coated comprises a first surface and an outer peripheral surface surrounding a periphery of the first surface perpendicular to a vertical direction, the flow-coating apparatus comprising:

• a first flow-coating mechanism, wherein a flow-coating opening of the first flow-coating mechanism faces the first surface and is configured to flow-coat the first surface with the insulation layer;
• a second flow-coating mechanism, wherein a flow-coating opening of the second flow-coating mechanism faces the outer peripheral surface and is configured to flow-coat the outer peripheral surface with the insulation layer;
• a rotation mechanism comprising a rotation cylinder or a drive motor, and configured to drive the member to be flow-coated to rotate around a central axis;
• a recycling groove located under the member to be flow-coated in the vertical direction and above the rotation mechanism in the vertical direction;
• a liquid supply mechanism comprising a hydraulic pump, wherein at least one of the first flow-coating mechanism or the second flow-coating mechanism communicates with the recycling groove via the hydraulic pump;
• and
• a gas suction mechanism located above the rotation mechanism in the vertical direction.
